摘要
总结了目前应用的霍尔元件式、接近开关式、光电耦合式等三类有线通信式绞车传感器的工作原理。针对录井有线通信式绞车传感器现场安装维护复杂、计数精度低、易受干扰的问题,利用无线传输技术和低功耗技术,设计一种信号发送节点,从脉冲信号处理、无线通信技术选择和供电设计等三方面对现有的绞车传感器进行改造。试验和现场应用表明,经过无线改造的绞车传感器解决了目前绞车传感器数据采集精度低、传输易受干扰的问题,具备了在钻井现场进行推广的要求,将极大促进无线钻井参数测量仪器的发展。
The principles of three types of sensors widely used in cable draw-works are summarized,which include the Hall element,proximity switch,optical coupler,etc. In view of the complex maintenance procedure,low counting accuracy and sensitivity to interference of cable draw-works sensors,a signal transmission node is designed based on wireless communication and low power technologies,and the cable draw-works sensors are modified aiming at the pulse signal processing,wireless communication selection and power supply mode.Experiment results and field applications indicate the new wireless draw-works sensors have solved low data acquisition accuracy and low stable transmission of the cable draw-works sensors,and reach satisfactory results. This improvement can promote the development of wireless drilling parameter measuring instruments.
